In this talk we provide an overview of the physics of the Lorentz model, in particular, we relax idealizing assumptions of the Lorentz model to investigate the robustness of the critical dynamics near the localization transition. First, we introduce obstacle correlations by using frozen-in hard-sphere fluids as realistic host structures, thereby changing the statistics of channel widths for the tracer particle. Second, we gradually change the microscopic dynamics from ballistic to Brownian which affects the rules how narrow channels in the system are probed. Our results confirm that the microscopic dynamics can dominate the relaxational behavior even at long times in striking contrast to glassy dynamics.
